摘要
运用受弯构件全过程数值分析计算程序,在预应力混凝土空心板截面尺寸及荷载形式相同,配筋率、跨高比、张拉控制应力、钢筋强度等参数不变的情况下,改变混凝土强度,对中强螺旋肋钢丝预应力混凝土空心板进行受力全过程的数值分析,即采用数值分析方法,探讨了混凝土强度对中强螺旋肋钢丝预应力混凝土空心板延性的影响。
The calculation procedure of numerical simulation was used and the whole process of loading bending slab was analysed, and the in- fluencing concrete strength to the ductile property ofprecast prestressed concrete slab with mid-strength spiral-rib steel wire was get from the ex- periment.In the process, changing the concrete strength, keeping the section and loading and some parameters constant, such as percentage of steel, span-height ratio, control tension stress, strength of reinforcing bars, and the conclusion can be get.
